Transceiver Channel Locations
The HardCopy IV GX transceivers are structured into full-duplex (Transmitter and
Receiver) four-channel groups called transceiver blocks. The total number of
transceiver channels and the location of transceiver blocks varies from device to
device.
Table 1–1 summarizes the total number of transceiver channels and transceiver block
locations in each HardCopy IV GX device member.
